IllegalArgumentException in maven-resources-plugin during deploy goal

I am trying to build my spring-boot application using maven using below command.

mvn -X -Dmaven.test.skip=true deploy

During this step, maven-resources-plugin tries to copy my application.yaml file to my targetclasses folder. And this fails with an IllegalArgumentException.

Relevant part of the stack trace.

[INFO] Copying 1 resource
[DEBUG] Copying file application.yaml
[DEBUG] file application.yaml has a filtered file extension
[DEBUG] Using 'UTF-8' encoding to copy filtered resource 'application.yaml'.
[DEBUG] filtering XXXsrcmainresourcesapplication.yaml to XXXtargetclassesapplication.yaml

Caused by: java.lang.IllegalArgumentException

    at org.apache.maven.plugins.resources.ResourcesMojo.execute (ResourcesMojo.java:356)

Any ideas on why this is failing? How can I ensure that my file gets copied?

My build succeeds if I delete my yaml file from resources folder!

Answer

Finally found the issue with this. When we were packaging the application, we were using the maven-dependency-plugin to copy two artifact classes to a single classes folder. And both the artifacts had their own application.yaml file. This was causing this error. Hope this helps for anyone who encounters something similar.
